As long as you learn to find more accurate acupoints, you will be more comfortable and healthier when you massage. Some acupoints on the soles of the feet are not randomly pressed, and they can only be operated according to relevant books.
Secondly, you can go to a pedicure shop to find a professional pedicure to help you massage. They are all professionally trained. After several years of practice, their massage is absolutely just right. They know which acupoints are healthier to press. What kind of strength the hand gives is beneficial to the human body and will also make you like to massage the soles of your feet.
Third, you can also apply for professional training courses. Now there are institutions specializing in foot massage. You spend thousands of dollars to study, not only to benefit yourself, but also to master a craft. If one day you don't like your present job, you can open your own pedicure shop.
